AUGER.

Specification of Letters Patent.

Patented Sept. 26, 1916.

Application filed May 15, 1915, Serial No. 28,392. Renewed February 9,1916. Serial No. 77,349.

To all whom it may concern Be it known that I, JOHN CALVIN Scrrmnon, acitizen of the United States, residing at Silverton, in the county ofMarion and State of Oregon, have invented certain new and usefulImprovements in Augers; and I do hereby declare the. following to be a.full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to new and useful improvements in augers and moreparticularly to that class adapted to be used for digging post holes,and my object is to provide means for adjusting the cutting bladeswhereby holes of various diameters may be produced.

A further object is to provide a ratchet construction at the upper endof the auger whereby the auger may be operated when in position adjacentan object.

Other objects and advantages will be hereinafter set forth and moreparticularly pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application,Figure 1 is a side elevation of the auger showing the cutting bladesthereof in extended position by dotted lines. Fig. 2 is a detailsectional view as seen on line 22 of Fig. 1. Fig. 3 is a transversesectional view through the construction at the upper end of the augerstem, and Fig. 4 is a detailed sectional view as seen on line H of Fig.1.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicates a stem tothe lower end of which is secured the frame portion 2 of the auger, saidframe consisting of downwardly and outwardly projecting arms 3, theupper faces of which are provided with channels 41, and adjustablymounted in said channels are the shanks 5 of the cutting blades 6, saidcutting blades being constructed in the usual or any preferred mannerand hinged together at their lower ends.

The shanks 5 are provided with longitudinal slots 7, through whichextend adjusting bolts 8, said bolts being extended through openings 9in the arms 3 and by extending the slots 7 substantially the full lengthof said shanks, the cutting blades 6 may be adjusted inwardly oroutwardly to produce openings of various diameters.

The upper end of the stem 1 is preferably constructed square in crosssection and enters the square opening 12 of a ratchet wheel 13 so thatsaid wheel and stem will rotate in unison. Immediately above the ratchet13, the stem is reduced in size and formed circular, thus providing astud 1% upon which is rotatably mounted a plate 15, said plate beingoblong in general outline and having adjacent its ends integral ears 16through which extends any suitable form of handle bar 17. To the underface of the plate 15 is pivotally attached a pawl 18 which is normallyheld in engagement with the ratchet wheel 13 by means of a spring 19.

By mounting the handle bar in the manner shown, it can be used forrotating the auger in the usual manner, that is to say, by disposing theends of the bar at equal distances on opposite sides of the stem andalternately grasping the ends of the bar to impart rotating motion tothe auger.

In some instances, as when a hole is being bored adjacent a fence orwall, it is necessary to position the auger so close to the object thatthe handle bar could not be given a complete rotation, but by providingthe ratchet and pawl, the handle bar can be moved to the position shownin dotted lines in Fig. 1 and the auger rotated by swinging the free endof the handle bar back and forth, the pawl riding over the ratchet whenthe handle bar is swung in one direction and imparting rotating movementto the auger when the handle bar is swung in the opposite direction. Inthis manner, the auger can be positioned in close proximity to an objectand the hole bored as readily as under normal conditions and it is notnecessary for the operator to release his grip upon the handle bar whenthe ratchet mechanism is employed for rotating the auger, thus savingtime and exertion.

What I claim is An auger comprising a stem, a frame attached to the stemprovided with project ing channeled arms, cutting blades hinged name tothis specification in the presence together at their lower ends andprovided of two subscribing Witnesses. with longitudinally slotted stemslocated JOHN CALVIN SCHLADOR in said channels, bolts for adjustably se-5 curing the stems in the channels, and means Witnesses:

for rotating the stem. P. L. BROWN,

In testimony whereof I have signed my GRACE M. BOYLES.
